Radial self-stabilizing reluctance magnetic bearing

open access: diamondProcedia CIRP, 2021
Abstract A novel design for a minimum loss reluctance magnetic bearing, with only one active control loop, will be presented in this paper. On the basis of extensive numerical simulations, the suitability of the bearing concept for machine tools and other possible applications are discussed. The results of the mostly finite element method simulations

Co‐excitation control of a four‐degree‐of‐freedom magnetic bearing switched reluctance motor based on mathematical models [PDF]

open access: goldIET Electric Power Applications
In traditional magnetic bearing motors, the magnetic bearing and the motor are usually driven and controlled separately, resulting in higher controller costs and limiting further expansion of their applications.

Position Sensorless Control of Switched Reluctance Motor under Magnetic Field Saturation [PDF]

open access: yesE3S Web of Conferences, 2021
When the switched reluctance motor is running, as the motor phase current increases, the magnetic circuit of the motor will gradually saturate, which affects the estimation of the special position of the motor rotor.
